IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 175,570, dated April 4, 1876 application filed February 2, 1876.

To all whom it may concern Be it known that I, FREDERICK LUNKEN- HEIMER, of Cincinnati, Hamilton county and State of Ohio, have invented an Improvement in Lubricators, of which the following is a specification My invention is designed to be applied to lubricators hax'ing glass shells or cases and exterior perforated metallic shields; and my invention consists in fitting the shield to the case in such a manner that it'will revolve freely, for the purpose of facilitating the cleaning of the glass, the shield being also of such construction that aspaee will be left between itself and the glass, to permit the shield to materially give way under a blow without imparting any pressure to the glass.

The accompanying drawing is a vertical sec tion of a lubricator embodying my invention.

A is the bottom of the cup, and B the hol low stem which supplies the oil to thecup through the apertures b. O is the top of the cup; D, a collared perforated nut to secure it in place, and E the plug which closes the feedaperture in the nut D. Both the top 0 and the bottom A have annular flanges c a, which surround the glass shell F, which is confined by the nut D between the gaskets G G, and these same flanges c a. form, upon their exterior surfaces, circular rests and guides, upon which the guard H fits and rotates. It has shown perforations through which the glass may be cleaned, the rotation of the guard giving every convenience for the cleaning of the glass all around.

The glass Fbeing inside of the annular shell affords a particular advantage in the rapidity and ease with which the glass reservoir may be cleaned all around. To do this it is only necessary to stuff a little cotton waste or a rag into one of the openings in the metallic shell, and then. to revolve the shell around the glass reservoir back and forth, applying a little pressure to the cotton waste with one finger. Were the shell stationary it would be necessary to clean the glass through each opening separately, which would not only be an awkward operation, but also consume considerable time in doing it.

I claim- A lubricator having a glass shell and a perforated metallic shield or guard therefor, adapted to rotate about the glass, and separated therefrom by an annular space, substantially as and for the purpose specified.

in testimony of which invention I hereunto set my hand.

FREDERICK LUNKENHEIMER.
